I'm loving this!
The framerate is *such* an improvement!
Also love the multi-word search. Integrated sign in and linking directly to edit.aspx from the synther is an interesting but probably necessary play for getting people to really engage.
I love that the geotagging now uses Seadragon for the maps. I, for one, would like an option in the editor to use overhead view as the initial visibility although that does create a question of which image to display for those who need to install Silverlight.
The thumbnail view of the map to the right of the synth in place of the globe icon is interesting. I like it but the colours begin to be a bit conflicted between the Photosynth motif, the global imagery, and the photos in the synth.

Speaking of colours... can we please, please (please!) get the ellipse in overhead view to either match the rest of the greens of Photosynth or use a colourless transparent icon? Right now it's just got too much blue in it unless you're going to be overhauling the colour design of the entire site, viewer icons, (and logo) soon.

We haven't touched the D3D viewer in months and months and won't be making any updates to it. We get much better reach with Silverlight without the install issues many people ran into with DirectX.
We're all a little sad about it, but the SL viewer is getting better all the time.

Instant fan. Seriously instant fan. Tony Ernst just let me know about the overhead view and about geoalign, and I just tried both on two of my synths. I'm with PGRic on the utility of overhead view for archaeology. CRIPES but this is nice.
I have noticed some oddness about altitude of the point cloud. My Kiholo Bay synth, for example, has the point cloud hovering in space when I test the geoalignment. But the alignment itself seems to work great, that one issue asside.
And the overhead view simply ROCKS. I seriously need to go back and align all my other synths.
Thanks guys! GREAT effort!
